Ow many sulfur atoms are in 1.10 mol of aluminum sulfide?

Aluminum sulfide is Al₂S₃, which shows that there are 3 sulfur atoms per formula unit.

In one mole there is Avogadro’s number of atoms and Avogadro’s number = 6.02 x 10²³

In 1.10 mole = 1.10 x 6.02x10²³ = 6.62 x 10²³ formula units

Now multiply with 3 to get number of sulfur atoms present in 1.10 mol of Aluminum sulfide;

3 x 6.62x10²³ = 1.99 x 10²⁴

So, the answer is 1.99 x 10²⁴ sulfur atoms.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
